The aperture 44 is preferably surrounded by a downwardly and inwardly turned flange 45 which, when the parts are in the position of Fig. 1, contacts and conforms` to the opposed flange 33. It will be understood that when the generator 40 is positioned preferably upon the support 8 and the support 8 is then elevated to its position of Fig. 1 by rotation of the rod I6, the apertures 32 and 44 constitute together a single passage between the fuel container 4G and the interior of the vaporizer 30. The springs i2 maintain the parts snugly together and permit a reasonable variation in dimensions. 50 indicates an internal compartment or propagator within the larger generator 40; it is illustrated as tubular or cylindrical, as wil-l be clear from Fig. 2. Its bottom may be open as at i. It has a slot or slots 52 in its sides which extend from adjacent the bottom to adjacent the top of the tube or chamber 50. It is shown as having an inclined-topewall 53 with a single outlet apern ture 54. The chamber 50 is secured i-nV place and supported within the fuel container 40 by means 'of the elbow member 55 and the transverse connecting pipe 56. The elbow 55 is suitably anchored on the top wa-ll 43 as at 51 and it connects with an upwardly extending air inlet tube 58. The tube has a top closure 59 and an air inlet aperture B0, adjacent its upper end. 6| indicates a suitable bimetallic leaf or element which carries at its end a closure 62 of proper form and material completely to close the aperture 60 when the 'parts are in the position of Fig. 1. The bimetal 6I may be mounted on the upper bend 64 of the supporting rod or wire 63, which also may be employed to hold the cap or top closure 59 in place. G6 is a coil spring about the top rod port tion 63 provided with an abutment 65, and formed Aand, adapted to maintain a thrust against the upper end of the bimetal 6I. It will be under stood that the bimetal, in response to changes in temperature of the adjacent combustion chamber 25, is formed and adapted to warp into and out of closing position, in such fashion as to maintain and control a variable flow of air through the aperture 60. The bimetal may be adjustably vset or limited by the threaded adjusting member' 61 with its exterior manual handle 68.

When it is desired to use the burner or heater, the parts are positioned as shown in Fig. 1. However, the user may readily remove the generator and propagator unit for cleaning, refilling, etc., as shown in Fig. 3. It is also preferably removed to the position of Fig. 3 when the user wishes to light it. When it is so removed, however, unless it is about to be lighted, it is desirable to close the fuel receptacle 40, to prevent escape of vaporized fuel. When the parts are in the position of Fig. 3, the bimetal 6| will move to the closed position, thus preventing any flow of vaporized fuel through the air inlet 6U. The user also may close the top aperture 44 by dropping the hinged closure 'l into place. The closure 'Hl with its arm 'H is pivoted as at 'l2 on any suitable collar or support 13 which surrounds a lower p0rtion of the air inlet tube 58.

It will be realized that, whereas I have described and claimed a practical and operative device, nevertheless many changes may be made in size, shape, number and disposition of parts without departing from the spirit of my invention. I therefore wish my description and drawings to be taken as in a large part illustrative or diagrammatic rather than as limiting me to my precise showing. It will be understood, for ex- 4 ample, that the tent support feature may be omitted. It will be further understood that the method of raising or lowering and supportnig the fuel container 4U may be widely varied.

'I'he use and operation of my invention are as follows:

I provide a flexible unit of relatively small weight which can be easily handled and transported and which can be readily demounted. For example, I have shown in Fig. 3, the fuel receptacle 40 may readily be removed. The tent support or adaptor and its upper parts may be readily removed, as they are shown as merely telescoped upon each other. The upper support 8 may be removed by disconnecting the pivots l0. The result is'a structure no component of which is of substantial weight or of too great size for easy handling.

With reference to the operation of the device, the generator 40 may be filled to a level just below aperture 54 with a volatile fuel such as gasoline. Its closure 'I0 is swung to the position in which it is shown in Fig. 1 and the container is positioned upon and within the angles I4 and l5 of the side support 3. Assume that it is rst lighted. It will be understood that the flame passes upwardly through the apertures 44 and 32 and into the interior of the vaporizer 30 and the combustion chamber 25. Air flows inwardly through the aperture 60 and along the tube 58 to the mixing chamber 50. The supply of air flows upwardly through the aperture 54 and also through the slot or slots 52 in the normal operation of the device. A primary mixture is provided by the air flowing through the tube 58 and mixing with the vaporized fuel, the primary mixture flowing upwardly into the vaporizer or mixing chamber 30. The chamber 36, with its 'perforated walls, adds further primary air to the mixture, full combustion taking place at or about the level'of the secondary air inlets 35. The rate of combustion can be varied by the manual control 61, 68, which operates against the bimetal or warping bar 6|.

In the use of my burner or tent heater the major advantage is the method of lighting. The fuel tank or generator tank 40 is lighted first, when removed from the rest of the assembly. It need be lighted only in one place, in contrast to ordinary orchard heaters, where the generator may be lighted at the top, and a propagator tube must also be lighted. After the generator has been lighted, it is moved into the position of Figure 1 and locked by the upward elevation of the support 8. I find it highly advantageous to employ the offset stack herein described and claimed. The herein described thermostat arrangement is also highly efficient in use.

I claim: l
